Primary/Secondary Master/Slave PIO
Each of these four items sets the mode timing according to the IDE hard disk
drives in your system. PIO means Programmed Input/Output. Rather than have
the BIOS issue a series of commands to effect a transfer to or from the disk
drive, PIO allows the BIOS to tell the controller what it wants and then let the
controller and the CPU perform the complete task by themselves. This is
simpler and more efficient (and faster). PIO mode concerns data transfer rate.
It can be mode 0 to 4. Higher number indicates faster rate.
Primary/Secondary Master/Slave UDMA
These items set if the IDE hard disk drive supports UDMA (Ultra 33 synchronous
DMA mode transfer).
IDE HDD Block Mode
This allows your hard disk controller to use the fast block mode to transfer data
to and from your hard disk drive.
Onboard FDD Controller
This item allows you to enable or disable the on-board floppy disk drive
controller.
Onboard Serial Port 1/2
This item sets the I/O address and interrupt request line (IRQ) for the on-board
serial port (COM1/2).
Onboard Parallel Port
This item sets the I/O address and interrupt request line (IRQ) for the on-board
parallel port (LPT1).
